You may be thinking of crude filament winding The state-of-the-art in filament winding is 6 axes numerically controlled, with the winding path...
I'll confess that I'm still confused about how to "match elongation" between the fiber and the resin. Your definition of elongation seems to be...
On 1. you are correct in the limited context of "what is the modulus of X composite". I tend to think of this in a different way: given fibers...
Sorry about the double counting, that should have been half the stiffness at same weight OR twice the weight at the same stiffness. Those were...
I'd be glad for an explanation of what I misunderstood about concrete. If you have a reference to a concrete structure that has more tensile...
jonr: You're absolutely correct; the suppliers of woven, mat, etc. I've found charge a substantial premium for S. The 20% price difference I...
Why isn't S glass used more? In rough terms, S glass is about 20% stronger, 20% stiffer, and 20% more expensive than E (ordinary) glass fiber....
Fiber Orientation is critical The problem with filament winding a large hull is that the main stresses are the stay and mast loads, so you want...
Depends... http://en.wikipedia.org/wiki/Ultimate_tensile_strength#Typical_tensile_strengths lists bamboo as having an Ultimate Tensile Strength...
